Place values and number sense Printable Lesson Plan for Teachers
Lesson Title:Place values and number sense
Lesson Objective: Students will understand place value concepts and use them to develop number sense by identifying the place value of digits in a given number, comparing and rounding numbers to the nearest ten, hundred and thousand.
Materials: Place value chart, base-ten blocks, place value worksheets, calculators (optional)
Introduction (5 minutes): Begin the lesson by reviewing the place value chart and asking students to identify the place values of different digits in a given number. Use base-ten blocks to demonstrate how numbers can be represented in different ways (e.g. 9 ones, 4 tens, etc.).
Direct Instruction (15 minutes): Using a whiteboard or overhead projector, demonstrate how to read and write numbers in standard, expanded, and word form. Show examples of how to use the place value chart to identify the value of a digit in a number. For example, if the number is 3,456, explain that the 3 is in the thousands place and has a value of 3,000.
Next, explain the concept of rounding numbers. Provide examples of rounding numbers to the nearest ten, hundred, and thousand. Ask students to identify the place value of the digit that needs to be rounded and the place value of the digit to which it is rounded.Guided Practice (20 minutes): Provide students with worksheets containing place value and rounding problems. Allow students to work on these problems with a partner or in small groups. Monitor their progress and provide assistance as needed.
Independent Practice (20 minutes): Give students more place value and rounding problems to work on independently. Encourage them to use a calculator if needed, but remind them to check their work and make sure their answers are reasonable. Encourage them to practice reading and writing numbers in standard, expanded, and word form and to use the place value chart to identify the value of a digit in a number.
Closure (5 minutes): Review the concepts covered in the lesson and ask students to share examples of place value and rounding problems they found challenging and how they solved them.
Assessment: Collect and review student worksheets to assess their understanding of place value and rounding concepts. Use a quick quiz or oral questioning to check their understanding of reading and writing numbers in different forms and their ability to round numbers.
